TYPE-WRITING MACHINE.

STEEGIFICATION forming part of Letters Patent No. 767,528, dated August 16, 1904.

Application filed September 26, 1901. Serial No. 76,671. (No model.)

To all whom it 77'bCt-Z/ concern:

Be it known that I, LEWIS H. PERRY, a citizen of the United States, and a resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-l/Vriting Machines, of which the following is a specification.

My invention relates to type-writing machines; and one of the objects of said invention is to provide simple and efficient line-lock mechanism therefor.

Another object of the invention is to provide means which will tend to prevent certain of the types-such, for instance, as those which have the period, comma, semicolon,&c. formed thereon-from puncturing the paper in the operation of the machine, as is ordinarily the case.

To the above and other ends, which will hereinafter appear, my invention consists in the novel arrangement and combination of parts and to the features of construction hereinafter described and claimed.

In the accompanyingdrawings, wherein one form or embodiment of my invention is shown and wherein like reference characters indicate like parts in the several views, Figure 1 is a vertical sectional View of a type-writing machine embodying my invention, the section being taken from front to rear of the machine. Fig. 2 is a plan view of the same. Fig. 3 is a front elevation of the machine, partly in section. Fig. 4 is an enlarged detail fragmentary sectional view illustrating a portion of the line-lock mechanism, the section being taken on the line 00 w of Fig. 3 and looking in the direction of the arrow at said line. Fig. 5 is a plan view of the same. Fig. 6 is an enlarged detail fragmentary sectional view ofa portion of the line-lock mechanism, the section being taken on the line y 1/ of Fig. 3 and looking in an opposite direction from the view shown in Fig. 4. Fig. 7 is a detail side view of one of the type bar actions which carries a punctuation-mark. Fig. 8 is an enlarged detail side view of a portion of the same. Fig. 9 is a fragmentary top view of the leaf-spring employed in this action. Fig. 10 is a transverse sectional View taken on 5 theline z 2 of Fig. 8.

In the various figures of the drawings parts have been omitted and broken away to more clearly illustrate other parts of the structure.

I have illustrated my invention in its application to a New Century Caligraph machine, although it should be understood that the invention or any one or more of the features thereof may be applied to other typewriting machines, and to this end various changes may be made in the structure.

The main frame of the machine is designated as 1, and this frame is provided with the usual top plate 2, and key-levers 3 are pivoted therein, as indicated at 4. Each key-le- 5 ver has a strap 5 secured thereto, which strap is pivoted at 5 to a link 6, that in turn is pivoted at 7 to an actuating-bar 8, which has one end of a contractile restoring-spring 8 secured thereto, the other end of said spring 7 being attached to a fixed hook 8, screwed to the frame of the machine. Each actuatingbar 8 is pivoted to and supported upon parallel links 9 10, which are in turn pivoted to fixed rods 9 and 10 respectively, that are secured to the frame 1, and a link 11 constitutes an intermediate connection between the actuating-bar 8 and the type bar or carrier 12. Each of the links 10 is provided with a locking hook or abutment 13, which swings with the link when a key-lever 3 is depressed, and cooperating with all of the locking hooks or abutments 13 is a locking-bar 14, which extends from side to side of the machine and may be pivoted at 14 to the frame thereof. 5 Upon reference to Figs. 3, 4, and 5 of the drawings it will be seen that this locking-bar 14 is connected to a link 15, as shown at 16, and the opposite end of this link is attached at 17 to a crank-arm 18, that is secured to a 9 rock-shaft 19, which turnsin a suitable bracket 20, attached to the framing of the machine at 21. This rock-shaft 19 is likewise provided with a crank-arm 22, to which is pivoted a longitudinally-extending rod 23. The height of the rock-shaft 19 is such that the upper end thereof will extend above the top plate2 of the machine, as represented in Fig. 3, so that the longitudinal ly-extending bar 23 moves above the top plate and projects through a stud 24, which is carried by a stop 25, and this stop 25 be rigidly secured to the rod by a screw 26. The free end of the rod 23 likewise projects through a stud 27, that is carried by an arm 28, which is pivoted at 29, as shown in Figs. 1, 2, and 5. This arm 28 is normally maintained in the elevated position by a coiled spring 30, which surrounds an extended end of the pivot 29 and is secured thereto at one end, as shown at 31, and has its opposite end secured to the arm 28, as shown at 32. hen the parts are in the normal position, the stop 25 extends into the path of one or more cooperating stops 33, which are adjustable along the supporting rack-bar 34, which is carried by the platen-carriage and a portion of which is represented at in Fig. 1. The arm 28 may likewise be provided with an abutment or stop 36, which extends into the path of the adjustable stop or stops 33, carried by the carriage, and the right-hand side 37 of this stop 36 is beveled, so that when a stop 33 moves from right to left and is permitted to reach contact therewith it will cause the entire arm 28 to be depressed at its free end, thus enabling the carriage to pass freely from right to left beyond the stop 36. hen, however, the carriage is moved in an opposite direction, the carriage-stops will contact with the straight face 38 of the relatively fixed stop 36 and will limit the movement of the carriage toward the right, thus providing a marl gin-stop for the machine. It should be understood that in practice the stop 33 on the right-hand side of the carriage will first cooperate with suitable trip mechanism (not shown) in order to sound the alarm, and the carriage will then be brought into contact with the line-lock stop 25, which will causeit to be moved a short distance to the left or until it reaches contact with the stop 36, mounted on the bracket 28, when the carriage will be arrested, and further movement from right to left will be prevented, all as more fully shown and described in the patent to C. D. \Vallace, No. 669,293, dated March 5, 1901. This movement transmitted to the line-lock stop 25 will cause the longitudinally-extending rod 23 to be moved with it, thereby transmitting motion to the rock-shaft 19, which is moved against the tension of its spring 39, that is secured at one end to the top plate of the machine, as indicated at 40, and at its opposite end to the rock-shaft, as shown at 41.

This movement of the roek-shaft around its longitudinal axis will transmit a rocking movement to the arm 18, secured thereto, and from the arm 16 to the link 15 and from thence to the locking-bar 14 to cause it to be forced toward the rear of the machine and into the position indicated in Fig. 4, wherein it will be observed that the locking-bar is in contact with the upper sides of all of the actuating-bars 8, which afford an additional support for the locking-bar. It will be observed that when the locking-bar is in this position it is in an effective engagement with all of the locking hooks or abutments 13, thus preventing a movement of any of the typebar actions. When the carriage is moved toward the right and so that the carriage-stop will be moved away from the line-lock stop 25, the spring 39 will be effective to restore the line-lock mechanism to its normal position and to withdraw the locking-bar from engagement with the hooks, and the various type-bar actions are free to be operated.

I have provided a separate line-lock mechanism for the spacing-key, which mechanism is, however, controlled inits movement by the line-lock mechanism for the key-levers of the type-carriers. The spacing-key is shown at 42 and is secured to key-levers 43, which are pivoted to the framing-of the machine upon opposite sides at 44. The pivot of each keylever of the spacing bar or key is intermediate of its ends, and the free end of each keylever is pivoted at 45 to the free end of a sec ond lever 46, which in turn is pivoted to the frame of the machine at each side thereof, as shown at 47. WVhile I have regarded the parts 43 and 46 in the nature of separate levers, they are, in fact, projecting arms of two oppositely-disposed yokes, each member 46 of the spacing-bar being notched at 48 and adapted to cooperate with a depending yoke 49, which is pivoted at 4. The lower crossbar 50 of this yoke only extends beneath its lever 46, a separate yoke being provided for each member 46 of the key-lever system of the spacingbar. Each yoke 49 extends upwardly at both ends beyond its pivot and is united at each end by a pin-and-slot connection 51 to a three-arm link 02, which is in turn pivoted to the framing of the machine, as shown at 53, and the third arm of this lever 52 is united to the depending arms 54 of the locking-bar 14 by a pin-and-slot connection 55. i

From the foregoing description and. an examination of Fig. 1 it will be observed that when the parts are in the normal position each bar 50, which constitutes a part of what may be termed a key-lever line-lock, is opposite the notched or indentured portion 48 of its lever 46, so that the rear end of said lever may be depressed to effect a feed movement of the carriage. \Vhen, however, the locking-bar 14 has been shifted from the position represented in Fig. 1 to that shown in Fig. 6, the space-key line-locks will be moved away from the notched portions 48 in the levers 46 and will cooperate with the under face or edge of the levers to prevent a depression of the rear ends thereof. It will be seen, therefore,

that when the key-lever line-lock is operated ICC to lock the key-levers against movement a like looking movement will be transmitted to the space-key locks to prevent a depression of the space-key and that when the key-lever line-lock is released an Unlocking movement will be transmitted to the locking mechanism for the space-key.

It is desirable'at times to release the keys after they have been locked by the line-lock mechanism in order to Write one or more letters or words on the same line. In order to accomplish this end, I have provided a handoperated releasing device for releasing the line-locking mechanism from engagement after it has been automatically engaged by the movement of the carriage. This hand-operated releasing mechanismcomprises a key or button 56, which extends above the top plate 2 of the machine and is secured to amovable stem 57, which is connected to a lever 58, that extends from the front to the rear of the machine and is bent, as indicated at dotted lines in Fig. 2, so as to project into the path of an antifriction-roller 59, carried by a depending arm 60, that is connected to the arm 28 and moves therewith around the pivot 29, the parts being supported by the stand or bracket 62. The bar 58 is pivoted at 63 to a depending lug or projection 64, secured to the under face of the top plate, and the rear end of this bar or lever 58 is provided with an inclined or beveled face 65, which cooperates With the antifriction-roller 59 referred to. The arms 60 and 28 and the parts carried thereby are maintained in the normal position (represented in Fig. 1 of the drawings) by the spring-80, hereinbefore described, and a depression of the button 56 will cause the rear end of the bar or lever 58 to be elevated, thus moving the lower end of the arm 60 in the direction of the arrow in Fig. 1, thereby causing the forward end of thearm 28 to be depressed, so as to convey thestops 25 and 36, carried thereby, out of the path of the cooperating stops 33 on the platen-carriage. hen the stops 25 and 36 have been depressed in the manner described, they no longer afiord an obstruction to the free movement of the carriage, and should the stops be in engagement a depression of the line-lock stop will release the line-locking mechanism, and the parts are restored to the normal position, by the spring 39, and the machine is free to be operated as before the locking engagement took place, and characters may be added to the line of print.

Another feature of my invention relates to means for preventing the types carrying the punctuation-marks and other sharp characters from puncturing the paper in the operation of the machine. This mechanism is illustrated in detail in Figs. 7, 8, 9, and 10, wherein it will be seen that the key-levers 3 of which one is employed for the period type-bar 12 for instance, are key-levers of the second'order, and each consists, preferably, of asingle piece like the key-levers 8. By single piece I mean a key-lever which is rigid through out its length, and With this in mind the keylevers 3 may be made up of several pieces. Instead of being fixed to oscillate upon the pivotal rod 4, each key-lever 3 is cut away at 66 to form an open-mouthed bearing that extends down from the pivotal rod or fixed fulcrum, so that the key-lever may ride up on its pivot 4, as illustrated in dotted lines in Fig. 7, under certain contingencies which will be described. On each side of each of these key-levers is mounted a guiding-plate 67 to prevent the key-lever from being displaced laterally and to guide it in its movement from the full-line to the dotted-line position. (Represented in Fig. 7 of the drawings.) Each of these keylevers is provided with a strap 68, which surrounds it and unites a leaf-spring 69 thereto, and this leaf-spring is secured at one end to a fixed portion of the machine, whereas its opposite end is bifurcated, as represented at 7 O, for cooperation With a notch 71 in the keylever 3". The strap 68 may be adjusted along the key-lever 3 to vary the tension of the spring 69 in operation and in order to regulate the touch to accommodate the machine to different operators. Thus if the strap is moved toward the rear of the machine it will shorten the effective portion of the spring between the strap and the fixed bearing of the spring, and a stifier spring Will be provided to accommodate an operator with a quick, sharp, and heavy stroke. A movement of the strap in the opposite direction Will reverse the effect. The other elements of each of these actions for the punctuation-marks are connected in the same manner as the other typecarriers hereinbefore described. Thus a strap 5 is secured to the key-lever 3 and pivoted to this strap is a link 6, which in turn is pivoted at 7 to a spring-restored actuating-bar 8, that is supported upon links 9 and 10, the latter of which is provided with a locking hook or abutment 18, which is adapted to cooperate with the locking-bar 14 in the same manner as the locking-abutments on the other type IIO actions, and between the actuating-bar 8 and the type-bar 12 is a link 11. In operation a depression of a key-lever 8 will cause the cooperating type-bar to be moved tothe printing position. (Indicated in dotted lines in Fig. 7 Any undue pressure or sharp stroke exerted upon the key will cause the rear end of the key-lever to be elevated and the key-lever itself to be depressed against the tension of the spring 69, and the resilient resistance thus afforded to the key'will take up a portion of the forceapplied to the key and will enable it to be depressed in the same manner and with the same force as the other keys Without, however, transmitting the force to a like extent to the type-bar, thereby preventing the type from puncturing the paper and at the same time providing a type-bar action that is easy and elastic in operation and which will not shock or jar the fingers of the operator.

\Vhile the results generally stated above will be attained under various conditions, the operation differs somewhat in accordance with the peculiarities of touch and stroke of different operators. Thus, for instance, if the operator has aslow and long following stroke the keylever may move around its fixed fulcrum 4 until the type-bar reaches the paper, when any further pressure on the key will cause the inner or rear end of the key-lever to ride up on the fulcrum 4 and against the tension of the spring 69. This is due to the fact that the platen acts as a positive resistance at this time to further movement of the type-bar, and hence the key-lever will turn on its pivotal connection 5 with the link 6 of the typcaction and the lever will rock away from its fixed fulcrum 4. If, on the other hand, the operator has a quick sharp touch, the tension of the spring 69 may be overcome before the resistance due to the weight of the type-bar can be overcome, in which event the key-lever will move away from its fixed fulcrum 4 at the initial portion of the stroke, and as the type-bar moves and the resistance thereof to the downward movement of the key-lever decreases the lever will be reseated on its fulcrum t by the spring 69.

From the foregoing it will be understood that each key-lever of the actions which carry the punctuation-marks has in a sense two fulcrum-points viz one, the pivot at, which is effective during a portion of the downstroke of the key-lever and another around the pivot 5-and both of which may become effective during the movement of the type-bar to the printing-point, depending on the character of the operators touch. In practice this movement of the key-lever around different fulcrum-points may not be apparent. Thus during the rapid operation of the machine and when a punctuation-key is depressed with considerable force the upward movement of the inner end of the lever and the movement of the lever around the pivot 5 may be substantially simultaneous. In any event, however, undue pressure exerted on the finger-key will not be transmitted to the type, and puncturing is avoided and an elastic touch afforded.

IVhile I have shown and described one form or embodiment of my invention, it should be understood that various changes in the structure may be made without departing from the spirit of my invention and that any one of the various features of invention may be used without the others.

An action for type-writing machines comprising a single-piece key-lever which has sepa ate fulcrum points around which it moves during a depression of the key-lever, a type-carrier, and intermediate connection between said type-carrier and key-lever,substantially as and for the purposes specified.

27. An action for type-writing machines comprising a type-carrier and an operativelyconnected single-piece key-lever which has separate fulcrum points around which it moves during a depression of the key-lever, the key-lever moving around one fulcrumpoint during one portion of the movement of the carrier to the printing-point and around another fulcrunrpoint during another portion of the movement of the carrier toward the printing-point.

28. An action for typewriting machines comprising a single-piece key-lever which has separate fulcrum points around which it moves during a depression of the key-lever,

one of said fulcrum -points being fixed and another resilient.

29. The combination of a type-carrier, a key-lever of the second order, having a fixed fulcrum, and means for affording a free movement of the key-lever away from said fulcrum during a depression of the key-lever, so that the full force of the power applied to the key-lever may not be transmitted to the typecarrier when said free movement takes place.

30. The combination of a type-carrier, a key-lever fulcrum, and akey-lever which has a bearing portion and an opening that extends downwardly from the bearing portion and permits a movement of key-lever away from the fulcrum during a depression of the key-lever.

31. The combination of a type-carrier, and a key-lever which has two fulcrum-points, the parts being constructed and arranged so that the key-lever will turn on one or the other of said fulcrum-points in accordance with the amount of force exerted upon said key-lever.

32. The combination of a type-carrier, a key-lever which has two fulcrum-points on one of which primarily it turns during the depression of the key-lever, and means which permit the key-lever to turn on the other of said fulcrum-points after the type-carrier has been moved to the printing position.

33. In a type-Writing machine, the combination of a type-carrier, a key-lever operatively connected thereto, means for permitting the key-lever to yield at its bearing during a movement of the carrier to printing position, and means for regulating the extent of resistance of the key-lever.
